In the balearics, we are bound by licence terms to provide everything in 4 languages.
Everything.. from house rules to house operations, to operating instructions for appliances, to tips and local things to do, TV stations, Radio Stations, right down to the labels on various switches ... is written in German, Spanish, French, and English.
We also speak German and Spanish. French is pretty rough for us, but we can get by.
Not that in any practical sense, it matters so much, as Germans (our most frequent guest nationality) tend to be fluent in English. Spanish and French guests less so.
Personally I think it's a good policy. It makes guests feel more comfortable, it enhances, safety, and that helps with ratings.
